Twin index

A twinning operation overlaps both the direct and reciprocal lattices of the individuals that form a twin; consequently, the nodes of the individual lattices are overlapped (restored) to some extent (overlap of lattices). The reciprocal n of the fraction 1/n of (quasi)restored nodes is called twin index
